  • the unlicensed band can be designated as a secondary CC. Offloading data traffic to a secondary CC in the unlicensed band can potentially provide a very efficient way for having LTE operate in both licensed and unlicensed bands simultaneously. But this raises the issue of coexistence given the nature of the unlicensed band.

  • X2 interface between the eNB and each of the APs for exchanging control information and user data going to and from the UEs and their respective APs.
  • the same operator of the eNB is also operating the APs, and in another example there are different operators who are all cooperating according to these teachings to facilitate coexistence.
  • Neither operational model has an effect on how these teachings are implemented.
  • the network operator will have clear knowledge of the geographic location of the LTE APs, which for brevity may be referred to as a geographical map.
  • the specific examples below assume the former model above, that the same operator runs both the eNB operating in the licensed band (termed the LTE eNB) and the relevant APs (each termed an LTE AP) operating in the unlicensed band.
  • the local area LTE APs are utilized for active feedback concerning the status of the unlicensed band. It is through this feedback that the LTE APs aid in the network operator's management of offloading traffic from the LTE eNB and from the licensed band.
  • the LTE eNB uses this feedback reported to it by the LTE APs, and in some embodiments also by the UEs which are operating with the LTE APs in the unlicensed band, to manage the spectrum usage among LTE APs which have overlapping coverage such as AP#2, AP#3 and AP#4 in Figure IB.
  • One UE is shown at Figure IB by example as being within the coverage area of the LTE eNB.
  • the UEs noted above which can participate in the active feedback would instead be located within the coverage area of any of the LTE APs.
  • Such a UE is assumed to have a radio connection with its respective LTE AP in the unlicensed band and also with the LTE eNB in the licensed band. That dual coverage may be simultaneous in which case the UE will have (at least) two radio frequency (RF) chains or the dual coverage may be time division multiplexed between the licensed and unlicensed bands in which case the UE may have only one radio.
  • RF radio frequency
  • the LTE eNB operating in the licensed band can be used to distribute frequency allocation information for the unlicensed band to the different LTE APs, such as via the X2 interface noted for Figure IB.
  • the LTE eNB has a geographic map with the locations of all the LTE APs under its control and uses this information at block 202 of the Figure 2 signaling diagram in making its initial frequency allocation. Since in this description there is not yet any feedback, consider this an initial frequency allocation, which the LTE eNB communicates to the various LTE APs at message 204 of Figure 2.
  • Figure 2 shows only one LTE AP but the LTE eNB sends similar allocation messages to the others.
  • the LTE eNB will divide the unlicensed band into carriers and allocate different (frequency distinct) carriers to those LTE APs whose geographic locations are close to one another.
  • LTE AP#2, AP#3 and AP#4 have overlapped coverage areas, so for example the LTE eNB can initially allocate carrier 1 for LTE AP #2, carrier 2 for LTE AP #3 and carrier 3 for LTE AP #4.
  • the LTE eNB can, if available, allocate a group of frequencies to one LTE AP, for example, carriers 1-4 to LTE #2, carriers 5-8 to LTE AP #3 and carriers 9-12 for LTE AP #4.
  • the LTE eNB will in this frequency allocation indicate the priority of the different frequencies for each LTE AP to minimize the possible interference among different LTE APs.
  • One criterion by which the LTE eNB establishes these priorities can be maximizing the frequency distance. So for example if carriers 4 and 5 are nearest to one another for the above allocation to LTE AP#2 and AP#3, this criterion would tend to reduce the priority of those carriers. As will be seen, these priorities are dynamically updated.
  • the frequency allocation is in certain embodiments of these teachings is dynamically adjustable based on the measurements that the LTE eNB receives from the LTE APs.
  • the reporting LTE AP will be measuring the channel conditions at its allocated carriers, and in some embodiments will also be measuring and reporting on unallocated carriers. Collecting these measurements is shown for the LTE AP at block 206 of Figure 2.
  • the LTE AP would report this to the LTE eNB and the LTE eNB will re-assess that carrier's priority. Most likely that re-assessment in light of interference will put that carrier in a lower priority, or the carrier will be completed removed from the allocation list for at least that LTE AP reporting the interference.
  • the LTE eNB may re-allocate that interfered carrier to another LTE AP, so for example if LTE AP#1 reported interference on carrier 1 the LTE eNB may choose to remove carrier 1 from the allocation to LTE AP#1 and add it to the allocation for LTE AP#4 which is geographically far enough that WiFi interference at LTE AP#1 should not be a factor for LTE AP#4.
  • the LTE eNB sends at message 204 an initial frequency allocation to the LTE APs. After receiving the initial allocation information, the LTE APs start to measure the interference level at block 206, at least at the allocated frequencies.
  • the LTE AP will then send feedback to the LTE eNB, in the form of a measurement report 208 at Figure 2. Based on the feedback information from the illustrated LTE AP and from others, the LTE eNB will form the updated frequency allocation at block 210 and send that updated information at least to the affected LTE APs in message 212.
  • the LTE AP will measure the frequencies which it is allocated. If the LTE AP has the capability of measuring frequencies outside of the allocation, the LTE AP can in an exemplary embodiment include a frequency recommendation or proposal in the measurement report 208 as well. With this information the LTE eNB can expand the list of available channels.
  • the measurement report 208 includes as well information or even a model of other user traffic, to facilitate the frequency allocation decision at the LTE eNB.
  • this additional information or traffic model is not routinely included in the measurement report which typically gives the interference level and possibly also throughput.
  • Other routine measurements can also be included in a typical measurement report 208.
  • the traffic modeling data can be included for example upon request by the LTE eNB.
  • the measurements can be carried out periodically, or alternatively or additionally they may be based on some trigger criterion. For example, new measurements and a new non-periodic report may be an increased number of retransmissions over some predetermined threshold, an increased packet loss rate over a threshold, and the like.
  • the measurement report from the LTE AP indicates one or more preferences for the different frequencies it reports. Additionally or alternatively the measurement report 208 can indicate an estimated capacity which the LTE AP can handle on its allocated frequency bands, preferably on a per carrier basis if more than one carrier is allocated to the reporting LTE AP.
  • the measurement report 208 from the LTE AP can in certain embodiments include, in addition to its normal measurement information about its actual measurement data, any one or more of the following:
  • the LTE AP can signal its recommended priority based on any potential information it has collected itself or that it obtains from other devices in its environment.
  • the LTE eNB can also collect measurements from some of the UEs attached to those LTE APs. The LTE eNB can use this further UE measurement information to improve the accuracy of its adjusted allocation, but this additional UE information is not necessary to practice the broader aspects of these teachings. For example, a given UE can measure the channel conditions it sees at different unlicensed bands. In this embodiment the UE reports its measurement results for the unlicensed band on the licensed band to the LTE eNB directly, since the assumption is that the licensed band is the UE's primary CC and the unlicensed band is its secondary CC.
  • the UE can report its measurement results for the unlicensed band on the unlicensed band to the LTE AP as well.
  • One clear advantage for including these UE measurements in the LTE eNB's computation of the allocation adjustment is that the interference level seen by the LTE AP may be different from that seen by the UE on the same frequency band and in the same geographic area, and so the different measurement perspective gives the LTE eNB a more precise view of the true channel conditions.
  • the LTE eNB can in one embodiment combine the measurement reports from the LTE AP and its UE(s) by having the UEs' measurement reports also classifying the channel as being either possible/available for transmission or having too much interference/not available.
  • the UE measurements would count in the same way as those from the LTE AP do, towards the estimated congestion on a channel in the area of a particular LTE AP.
  • the weighting will in this embodiment be a bit different; the weighting factor applied to the UE measurement would reduce its impact (for example, by dividing the UE measurement by a constant multiplier).
  • the LTE eNB can determine the availability of a certain channel at one of the LTE APs based on the information from both the LTE AP itself and from one or more of the UEs it serves.
  • the LTE eNB collects all of this data from the LTE APs with cooperate with it, and possibly also from some of the UEs, and does a frequency allocation adjustment and updates its allocation map at block 210 of Figure 2. Specifically, the LTE eNB seeks to control the load on the various LTE APs to which it is offloading traffic since in the carrier aggregation scenario the unlicensed band is being used as a secondary CC.
  • this load control is only over those LTE APs which are in cooperation with the LTE eNB and which send it measurement reports; the LTE eNB has no control over other entities operating in the unlicensed band such as conventional WiFi APs utilizing IEEE 802.11 radio access technologies but not cooperating for coexistence purposes with the LTE eNB.
  • the LTE eNB adjusts the frequency allocation and sends the new allocations to the LTE APs at message 212.
  • the content of this update frequency allocation 212 varies across different embodiments and implementations. But apart from that message 212, the LTE eNB can also, from that same information it has collected, then build what might be termed a deployment MAP which lists the current unlicensed band allocation and share this deployment map information with other neighbor cells and/or with the mobility management entity (MME) for higher-level coordination at the LTE eNB cell edge with other LTE eNBs that might also be practicing these teachings especially if the same LTE AP is connecting to multiple LTE eNBs.
  • MME mobility management entity
  • the LTE eNB can keep a table on the estimated congestion on each potential channel (such as for example the percentage of the observed times) when the channel in the unlicensed band has been observed or known to be unusable due to other traffic.
  • the congestion estimation can be updated based on every LTE AP measurement feedback, so for example if a new observation/measurement report signals that a channel is not available or "reserved", the congestion percentage for that channel is moved up by one step and vice versa if the indication tells that the channel is available or "free”.
  • the LTE eNB If the interference for a particular channel is higher than a predetermined threshold, the LTE eNB marks that particular channel as fully congested and it will not be used until further information in later measurement reports move the congestion level below the threshold. The LTE eNB would then update its allocation 210 so as to allocate traffic on each potential channel in proportion of the estimated congestion.
  • the measurement reports 208 indicates to the LTE AP some preference(s) for some certain frequency, that preferred frequency would then be allocated in the desired order of priority for that particular LTE AP, so long as it would not violate the procedure described above for congestion exceeding the threshold.
  • the LTE eNB can then base its final decision whether or not to offload traffic to a given LTE AP and unlicensed band channel based the information from all LTE APs, and from the UEs if they are also sending measurement reports.
  • the offloading strategy is decided at the system-wide level with better coexistence performance rather than only by looking at the status of only one LTE AP.
  • the LTE eNB would allocate traffic on each channel at the times with the highest expectation of the unlicensed band channel being free traffic. For example, the LTE eNB may use a dynamically tunable parameter which reflects how low of an expectation would not be tolerated and thus no traffic should be allocated.
  • the LTE eNB can use another parameter which reflects the capacity that can be offered in the different unlicensed channels.
  • the capacity can be estimated based for example on packet deliver latency, number of retransmission, history of channel usage, and so forth. Since the LTE eNB has information on the capacity of each channel of a certain LTE AP, this information can be used in the LTE eNB's determination of how much traffic can be offloaded to a certain channel at a certain LTE AP.
  • the LTE eNB can use the licensed frequencies as much as they are available for better quality of service (QoS) support.
  • QoS quality of service
  • the LTE eNB could move some of its traffic to the unlicensed bands based on its need using the secondary CCs. In that event the load on the unlicensed band to be put on all the LTE APs then depends on the estimated congestion/capacity which the LTE eNB learns from the measurement reports as detailed above.
  • the LTE eNB can take that into account when doing its load balancing and choosing channels and LTE APs to which to offload further traffic, putting the new load on higher performing APs in proportion to the differences in performance. If the LTE eNB would like to offer more capacity for some other purpose in the area of a particular LTE AP, the load of that LTE AP could then be balanced accordingly.
  • the LTE eNB can utilize the capacity estimation in the measurement reports from the different LTE APs to better balance the load among licensed eNB and unlicensed LTE APs.
  • the logic flow diagram of Figure 3 summarizes some of the various exemplary embodiments of the invention from the perspective of the cellular network node/LTE eNB (or certain components thereof if not performed by the entire eNB), and may be considered to illustrate the operation of a method, and a result of execution of a computer program stored in a computer readable memory, and a specific manner in which components of an electronic device are configured to cause that electronic device to operate, whether such an electronic device is the access node in full or one or more components thereof such as a modem, chipset, or the like.
  • Figure 3 begins at block 302 where the LTE eNB or other cellular network node collects information about at least interference in a plurality of channels in unlicensed spectrum. Then at block 304 it uses the collected information to update an allocation of the channels among at least two different access points.
  • Block 306 summarizes some of the above examples as to the information that is collected at block 302. Namely, in one embodiments the information is collected from measurement reports received from each of the access points; in another they also indicate whether the respective channel is available or reserved; in a still further embodiment there is also collected at least one further measurement report that the LTE eNB receives (directly) from a UE, and this UE based measurement report concerns at least one of the channels in the unlicensed spectrum yet is received by the LTE eNB over a wireless channel in licensed spectrum.

Abstract

Un nœud d'accès cellulaire collecte des informations concernant au moins un brouillage dans une pluralité de canaux dans un spectre sans licence, et utilise ces informations collectées pour mettre à jour une attribution des canaux parmi au moins deux points d'accès (AP) différents. Dans un mode de réalisation, les informations sont collectées dans des rapports de mesure reçus de chaque AP, qui indiquent si les divers canaux respectifs sont disponibles ou réservés. Des rapports de mesure supplémentaires peuvent être collectés dans des équipements utilisateurs fonctionnant sous les AP. Dans divers modes de réalisation, les informations peuvent comprendre des recommandations de canal, une capacité estimée pour les canaux, et/ou un modèle de trafic pour les canaux. Avec ces informations collectées, le nœud d'accès cellulaire peut équilibrer le trafic parmi les AP par ses décisions d'attribution de canal. Les exemples non restrictifs supposent un environnement radio dans lequel un nœud d'accès cellulaire LTE exploite une porteuse composante primaire dans un spectre sous licence et les AP coopérants exploitent des porteuses composantes secondaires dans un spectre sans licence.
